In a Kickstarter blog update, Pebble’s makers have said that the company will be “sending out the first batch to the very first backers this afternoon,” but warns backers that there are “still some kinks and issues that we need to work out.” The first batch is said to be less than 500 units, after initial shipments were delayed as a result of airport documentation.

The company has previously said that its production line can produce 15,000 watches per week.

Despite having been submitted more than two weeks ago, the Pebble iOS app has yet to be approved for the App Store. Recipients will therefore be able to only control notifications and music, but will not be able to upgrade their smartwatch or install watchfaces until the official iOS app is approved by Apple.

Android development is reported to be on track, and the app is expected to go live on the Play Store tomorrow.

Pebble Technology will ship more units “soon,” but wants to warn customers that they may have received their address confirmation notice ahead of the actual shipment, so there may be a delay until their watch arrives.
